hello
I have rooted my phone after the update to lolipop . I just now have a VW with premium system . So I have the rSAP (trial) installed. But the vehicle does not manufacture rSAP connection ??? Do you know why? it would work with the full version ?
sorry for my bad english

It's always the car which decides to use rSAP or not. The SIM check looks good and I don't think you have any Bluetooth problems.

What "Premium" phone do you have? The old version (Golf VI, ...) or the new one (Golf VII/new Passat, ... with nav system "Discover Pro")? In both case you should be able to manually switch to "Premium" mode, either with the steering wheel buttons (old) or in the nav screen.
